Loopring Bi-Weekly Update — 09/29/2019
|Matthew Finestone||Oct 1, 2019|
We have been testing the Lightcone relayer cluster, and identifying and fixing bugs. Lightcone’s integration testing and stress testing will remain our top priority in the coming months.
Research & Development
We have drafted the design for a Generic Extension for Request Validation (GERV) which will power features such as Conditional-Transfer which enables users to withdraw their balance as quickly as one Ethereum block time. GERV will enable developers to add functionalities and features to the Loopring protocol without modifying the protocol’s code-base. We need two more weeks to implement and test this feature.
We have also integrated Loopring 3.0 with Uniswap. Now Ether and tokens other than LRC in protocol fees can be swapped to LRC through Uniswap. The Loopring team has added 1000 Ether (and the corresponding LRC amount) to the LRC/ETH market on Uniswap to stabilize the LRC price.
We have finished some major components of the DEX browser, a tool for people to browse DEX activities based on-chain data-availability. Its persistence mode remains to be implemented/tested though.
Note: The current Lightcone relayer only supports Loopring 3.0-beta2.
We have deployed Loopring 3.0 on the Rinkeby testnet and a Lightcone relayer cluster to interact with it. We have fixed some bugs but there are still quite a few outstanding issues to be resolved. Our priority for the coming months remains to be the integration and stress testing of the relayer. An open challenge is to implement a better rollback strategy to handle unexpected errors. Our engineers have also started to support better log aggregation, service monitoring, and data visualization for the backend.
The construction of SNARK proofs in the cloud is more cost-efficient after all ZKP proving key files are hosted in the AWS Elastic File System which avoids the copying of large files.
Our engineers have also completed integrating Lightcone API into vnpy and HummingBot. Functionalities including order management and information querying are all ready; a few basic trading strategies are also available.
We have added a feature to export users’ trading key-pairs as encrypted files. The files can be given to a trader who then can trade on behalf of the account owners. We have also started to add support for beta3 which uses a different hashing function and signing algorithm.
